機動車輛的碟式煞車裝置之內襯墊固持系統 Liner retention system for disc brakes of motor vehicles 發明領域 Field of invention

本發明係有關一種機動車輛之碟式煞車裝置的內襯墊固持系統，特別是依據申請專利範圍第1項之前言部份的功能性車輛者。 The present invention relates to an inner liner retaining system for a disc brake device for a motor vehicle, and more particularly to a functional vehicle according to the preamble of claim 1 of the patent application.

發明背景 Background of the invention

該等碟式煞車裝置的內襯墊固持系統之各種構造變化係可由習知技術得知。 Various structural variations of the inner liner retaining system of the disc brake devices are known from the prior art.

該等煞車襯墊通常係被導設於一煞車器載體的襯墊軸中，並緊抵一煞車鉗上之一彎曲的襯墊固持構件，其會藉一襯墊固持彈簧延伸於該煞車器載體上。該襯墊固持彈簧會以一力FF將該煞車襯墊壓抵於該煞車器載體。當一煞車操作時，由於傳送至該煞車襯墊的扭力M，故該煞車襯墊可反抗於該襯墊固持彈簧的彈力而繞一旋轉點移動，於此情況下該旋轉點係位在該煞車器載體的出口側載體角件之一上端的區域中。 The brake pads are typically guided in a pad shaft of a brake carrier and abutting against a curved pad retaining member on a caliper that extends through the brake retaining spring to the brake device On the carrier. The pad retaining spring presses the brake pad against the brake carrier with a force F F . When a brake operation, due to the torque M transmitted to the brake pad, the brake pad can move around a rotation point against the elastic force of the pad retention spring, in which case the rotation point is in the In the region of the upper end of one of the outlet side carrier corners of the brake carrier.

因此，由於該煞車襯墊移動的結果，扭力可被傳至該煞車鉗之一壓力片及設在其上之一螺紋管，該煞車襯 墊的轉動可能導致不良的磨耗調整。 Therefore, as a result of the movement of the brake pad, the torque can be transmitted to one of the pressureps of the brake caliper and a threaded pipe provided thereon, the brake lining Rotation of the pad may result in poor wear adjustment.

為能防止該煞車鉗之此一轉動，將該煞車襯墊正鎖固定於一由該煞車器載體之載體角件及該煞車器載體之一會連接該等載體角件的橋片所形成的煞車襯墊軸中亦是不合宜的，因為該等煞車襯墊和煞車器載體之製造相關容差需要一最小的餘隙。 In order to prevent the rotation of the brake caliper, the brake pad is positively locked and fixed on a carrier angle piece of the brake carrier and a bridge piece connecting one of the brake carrier members to the carrier corner pieces. Brake pad shafts are also undesirable because the tolerances associated with the manufacture of the brake pads and the brake carrier require a minimum clearance.

發明概要 Summary of invention

本發明之一目的係為在一煞車操作時有效地阻止上述的煞車襯墊之轉動。 One of the objects of the present invention is to effectively prevent the rotation of the above-described brake pad during operation of a brake.

此目的係可藉一具有申請專利範圍第1項之特徵的機動車輛之碟式煞車裝置的襯墊固持系統來達成。 This object is achieved by a pad retaining system for a disc brake device of a motor vehicle having the features of claim 1 of the patent application.

一種以此方式構製的襯墊固持系統係區別在於至少有一襯墊固持彈簧設在該煞車襯墊面向該煞車器載體之橋部的一側與在該襯墊軸中之該煞車器載體的橋部之間，該襯墊固持彈簧在組合狀態時，會以一對抵該等載體角件沒有餘隙的方式將在該煞車器載體之橋部前方的煞車襯墊推離。 A pad retaining system constructed in this manner differs in that at least one pad retaining spring is disposed on a side of the brake pad facing the bridge of the brake carrier and the brake carrier in the pad axle Between the bridges, when the pad retaining springs are in the combined state, the brake pads in front of the bridge of the brake carrier are pushed away by a pair of the carrier corners without clearance.

由於以此一方式來設置該等襯墊固持彈簧，它們並非朝該煞車器載體之橋部的方向推壓該煞車襯墊，而是以一徑向相反的朝外方向，故該煞車襯墊會被以該力FF直接推壓形成該煞車襯墊與煞車器載體角件之間的正鎖連接；而在無施力狀態時，即是說，在一沒有煞車操作發生的狀態時，該煞車襯墊係被設成徑向朝外地與該等煞車器 載體角件正鎖連接，於此時，用以將該煞車襯墊裝入及移出該煞車襯墊軸所需的容隙會被提供，且一需要的熱膨脹補償亦會被確保。若一煞車操作現被促發，則該煞車襯墊只可能朝該出口側載體角件的區域傾斜，但是，此會由於該煞車襯墊側面靠抵於該出口側煞車器載體角件而被產生於該出口側煞車器載體角件處的摩擦力FR阻止。 Since the pad retaining springs are provided in such a manner that they do not urge the brake pad in the direction of the bridge of the brake carrier, but in a radially opposite outward direction, the brake pad Will be directly pushed by the force F F to form a positive lock connection between the brake pad and the brake carrier corner piece; and in the no-force state, that is, in a state where no brake operation occurs, The brake lining is configured to be positively locked radially outwardly with the brake carrier corner members, and at this time, the clearance required for loading and unloading the brake lining of the brake lining It is provided and a required thermal expansion compensation is also ensured. If a brake operation is now triggered, the brake pad may only be tilted toward the area of the exit side carrier corner member, but this may be caused by the side of the brake pad against the exit side brake carrier angle member. The friction force F R generated at the exit side brake carrier corner piece is prevented.

由於該煞車襯墊靠抵於該正鎖連接的徑向外側，故當扭力由於一煞車操作而被引入時，則該煞車襯墊的旋轉點會由該出口側載體角件朝向入口側載體角件移位，故該煞車襯墊之一沿該煞車碟之一主旋轉方向的旋轉運動會被有效地阻止。 Since the brake pad abuts against the radially outer side of the positive lock connection, when the torque is introduced due to a brake operation, the rotation point of the brake pad is directed from the outlet side carrier angle toward the inlet side carrier angle The piece is displaced, so that the rotational movement of one of the brake pads along the main direction of rotation of the brake disc is effectively prevented.

本發明之較佳的構造變化例係載述於依附項申請專利範圍中。 Preferred structural variations of the invention are set forth in the scope of the appended claims.

依據較佳的構造變化例，該襯墊固持彈簧係構成一薄片彈簧、一螺旋彈簧、一板彈簧，或亦可為一旋轉彈簧或扭力彈簧，其皆能夠在無煞車狀態時將該煞車襯墊正鎖連接在該等載體角件或該煞車襯墊的徑向外側。 According to a preferred embodiment of the structure, the pad retaining spring is configured as a leaf spring, a coil spring, a leaf spring, or a rotating spring or a torsion spring, which can be used for the brake lining in the no-brake state. A pad positive lock is attached radially outward of the carrier corner pieces or the brake pad.

依據一另擇的構造變化例，該襯墊固持系統係被以一方式構製，而使該襯墊固持彈簧被支撐在一彎曲的襯墊固持構件上，其係固定於該煞車鉗，而該煞車襯墊彈簧係構製成一拉力彈簧。利用本發明之此設計，該煞車襯墊亦能被以正鎖連接固持在該等載體角件的徑向外部區域，因此在煞車時所需的阻止旋轉作用亦能以此設計來有效地阻止。 According to an alternative structural variant, the pad retaining system is constructed in such a manner that the pad retaining spring is supported on a curved pad retaining member that is secured to the brake caliper, The brake pad spring is constructed as a tension spring. With the design of the present invention, the brake pad can also be held in a radially outer region of the carrier corners by a positive locking connection, so that the rotation preventing action required during braking can be effectively prevented by this design. .

較佳實施例之詳細說明 Detailed description of the preferred embodiment

在以下的圖式之描述中，譬如頂、底、左、右、前、後等用語，係僅為該固持系統、煞車器載體、襯墊固持彈簧及類似物等，在該各圖中所擇的舉例說明和位置。該等用語並非要被視為限制，即是說，由於不同操作位置或因鏡像對稱構形的結果等等，此等用語可能改變。 In the following description of the drawings, terms such as top, bottom, left, right, front, and rear are only the holding system, the brake carrier, the pad retaining spring, and the like, and the like in the drawings. An example and location of the choice. These terms are not to be considered as limiting, that is to say, such terms may change due to different operational positions or results due to mirror-symmetrical configurations.

圖1為一由習知技術所知的機動車輛之碟式煞車裝置的襯墊固持系統之前視圖。該襯墊固持系統具有一煞車器載體1具有二載體角件2、3，它們係藉一橋部4互相連接並一起形成一襯墊軸7，其中與一煞車碟(未示出)相關聯的煞車襯墊5等可被設在兩側。 1 is a front elevational view of a pad retention system for a disc brake device for a motor vehicle as known in the prior art. The pad retaining system has a brake carrier 1 having two carrier corner members 2, 3 which are interconnected by a bridge portion 4 and which together form a pad shaft 7, wherein associated with a brake disc (not shown) Brake pads 5 and the like can be provided on both sides.

該煞車襯墊5本身包含一襯墊載板51及一摩擦襯墊(未示出)其面對該煞車碟。 The brake pad 5 itself includes a pad carrier 51 and a friction pad (not shown) that faces the brake disc.

在組合狀態時，該等煞車襯墊會被用一襯墊固持彈簧6以一固定方式呈一彈性載壓狀態固持於該襯墊軸7 中。該襯墊固持彈簧6係固定於該煞車鉗(未示出)之一彎曲的襯墊固持構件8，並朝該載體橋4的方向以該彈力FF將該煞車襯墊5壓抵於該煞車器載體1。 In the assembled state, the brake pads are held in the pad shaft 7 in a fixed manner by a pad retaining spring 6 in a fixed manner. The pad retainer spring 6 fixed to the brake caliper system (not shown) holding one of a curved pad member 8, and the vector direction of the bridge 4 to the elastic force of the brake pad 5 F F pressed against the Brake carrier carrier 1.

若一煞車操作現被促發，則該煞車襯墊會被壓抵於該煞車碟，而由於該煞車碟以一主旋轉方向HDR的旋轉，一移動會反抗該襯墊固持彈簧之彈力並繞一旋轉點D轉動，該點D係位在出口側載體角件2的上端。為能阻止此旋轉移動，該煞車襯墊5與該煞車器載體1的載體角件2、3之一正鎖連接，例如藉在該襯墊載板51上形成側向凸體並在該等載體角件2、3面向該煞車襯墊5的內側處形成對應的凹部等，亦是不足夠妥當的，因為該等構件之製造相關容差需要一最小的餘隙。 If a brake operation is now triggered, the brake pad will be pressed against the brake disc, and as the brake disc rotates in a main rotational direction HDR, a movement will resist the elastic force of the spacer retaining spring and A rotation point D is rotated, and the point D is positioned at the upper end of the outlet side carrier corner member 2. In order to prevent this rotational movement, the brake pad 5 is positively coupled to one of the carrier corner members 2, 3 of the brake carrier 1, for example by forming a lateral projection on the pad carrier 51 and at the same It is also not sufficient for the carrier corner members 2, 3 to form corresponding recesses or the like at the inner side of the brake pad 5, since the manufacturing tolerances of the members require a minimum clearance.

圖2示出一依據本發明之機動車輛的襯墊固持系統之一第一較佳構造變化例。 2 shows a first preferred configuration variant of a pad retaining system for a motor vehicle in accordance with the present invention.

對比於圖1中所示的襯墊固持系統，該襯墊固持彈簧係被以一方式設成使在組合狀態時，其會以一沒有餘隙的方式對抵該等載體角件2、3將該煞車襯墊5推離該橋部4。 In contrast to the pad retaining system shown in Figure 1, the pad retaining springs are arranged in such a way that, in the assembled state, they will abut the carrier corners 2, 3 in a manner free of play. The brake pad 5 is pushed away from the bridge portion 4.

在圖2所示的構造變化例中，該襯墊固持彈簧係構製成一薄片彈簧，其係中央被扣持於一凹槽54中，該凹槽54係在該煞車襯墊5之襯墊載板51相反於該橋部4的一側57處，較好藉由一彎曲的固持構件61，其會垂直於該襯墊固持彈簧6的縱向伸幅而繞該彈簧6銜接。該襯墊固持彈簧6之二端部區62係支撐在該橋部4面向該煞車襯墊的上側，而以該力FF推壓該煞車襯墊5，且形成於襯墊載板51之側面 55、56上的凸體52、53會對抵該等載體角件2、3面向該煞車襯墊5之內側21、31處的凹部22、32之徑向外緣。 In the structural variation shown in FIG. 2, the pad retaining spring is configured as a leaf spring that is centrally held in a recess 54 that is lining the brake pad 5 The pad carrier 51 is opposite the side 57 of the bridge 4, preferably by a curved retaining member 61 that engages the spring 6 perpendicular to the longitudinal extent of the pad retaining spring 6. The two end portions 62 of the pad retaining spring 6 are supported on the upper side of the bridge portion 4 facing the brake pad, and the brake pad 5 is pressed by the force F F and formed on the pad carrier 51 The projections 52, 53 on the sides 55, 56 will abut the radial outer edges of the recesses 22, 32 of the carrier corners 2, 3 facing the inner sides 21, 31 of the brake pad 5.

在該煞車襯墊的下側57與該橋部4的上側之間，及在該等凹部22、32靠近該橋部4的區域與該襯墊載板51的凸體52、53之間，由該向上推壓的煞車襯墊5所造成的間隙71，會確保此一襯墊固持系統所需的熱膨脹補償，及該煞車襯墊5之組合和拆解需要的容差。 Between the lower side 57 of the brake pad and the upper side of the bridge 4, and between the areas of the recesses 22, 32 adjacent the bridge 4 and the projections 52, 53 of the pad carrier 51, The gap 71 created by the upwardly urged brake pad 5 ensures the thermal expansion compensation required for the pad retention system and the tolerances required for the combination and disassembly of the brake pad 5.

然而，一重大的優點會造成，由於該煞車襯墊係被以此一方式抬高，而使該煞車襯墊5現在會與載體角件2、3的凹部22、32徑向朝外靠抵，因此當一煞車操作時作用的扭力M會使該旋轉點D1由該出口側載體角件2的上緣移至該襯墊載板51的凸體53與入口側載體角件3之凹部32的接觸區域，由於該扭力M致生在該煞車襯墊5的出口側，故該煞車襯墊5將會以一徑向朝內的方向傾斜；但是，此會因該煞車襯墊5相對於該出口側載體角件2的側面55係緊抵該出口側載體角件2面向該煞車襯墊5的內側21而被阻止。由於此二側面55和21互相緊抵，故一摩擦力FR會作用反抗該扭力M，因此，以此方式，當一煞車操作時，該煞車襯墊5之一旋轉運動會被有效地阻止。 However, a significant advantage is that the brake pad 5 is now raised radially in this manner as the brake pad 5 is now raised radially outwardly from the recesses 22, 32 of the carrier corner members 2, 3. Therefore, the torsion force M acting when a vehicle is operated causes the rotation point D 1 to be moved from the upper edge of the outlet side carrier angle member 2 to the convex portion 53 of the pad carrier 51 and the recess of the inlet side carrier corner member 3. The contact area of 32, since the torque M is generated on the exit side of the brake pad 5, the brake pad 5 will be inclined in a radially inward direction; however, this will be relative to the brake pad 5 The side surface 55 of the outlet side carrier corner member 2 is fastened against the inner side 21 of the brake side carrier corner member 2 facing the brake pad 5 to be blocked. Since the two side faces 55 and 21 abut each other, a frictional force F R acts against the torsion M, and therefore, in this manner, one of the brake pads 5 is rotationally prevented when a brake is operated.

在圖3所示之依據本發明的襯墊固持系統之構造變化例中，該襯墊固持彈簧6亦被構製成一板彈簧，該襯墊固持彈簧6的端部區62係緊抵該煞車襯墊5的下側，而該構製如一板片彈簧之襯墊固持彈簧的中央區係被支撐在該橋部4上。 In the structural variation of the pad retaining system according to the present invention shown in FIG. 3, the pad retaining spring 6 is also configured as a leaf spring, the end region 62 of the pad retaining spring 6 is fastened thereto. The underside of the brake pad 5 is supported, and the central portion of the pad retaining spring, such as a leaf spring, is supported on the bridge 4.

在圖4所示之依據本發明的襯墊固持系統之構造變化例中，該襯墊固持彈簧係被構製成一螺旋彈簧，其中較好是針對每個該等煞車襯墊5設有二個此種螺旋彈簧，它們會對抵該橋部4向上推壓該煞車襯墊5來與該等載體角件2、3正鎖連接。 In the structural variation of the pad retaining system according to the present invention shown in FIG. 4, the pad retaining spring is configured as a coil spring, wherein preferably each of the brake pads 5 is provided with two Such coil springs, which push the brake pad 5 upward against the bridge 4, are positively coupled to the carrier corner members 2, 3.

在圖5所示之依據本發明的襯墊固持系統之構造變化例中，該襯墊固持彈簧6係構製成二板狀彈簧的形式，其如同圖4中所示的構造變化例，會抵住該橋部4的上側，而在該煞車襯墊的襯墊軸7中從該煞車襯墊5靠近入口側邊緣或出口側邊緣處的下側57推壓，來與該等載體角件2、3形成正鎖連接。 In the structural variation of the pad retaining system according to the present invention shown in FIG. 5, the pad retaining spring 6 is configured in the form of a two-plate spring, which is similar to the structural change shown in FIG. Abutting the upper side of the bridge portion 4, and pushing in the pad shaft 7 of the brake pad from the lower side 57 of the brake pad 5 near the inlet side edge or the outlet side edge, and the carrier corner pieces 2, 3 form a positive lock connection.

最後，圖6示出一依據本發明的襯墊固持系統之一構造變化例，其中該襯墊固持彈簧6係呈一扭力彈簧的形式，其係固定於該橋部4並會將該煞車襯墊5固持於該升高位置來與該等載體角件2、3形成正鎖連接。 Finally, FIG. 6 shows a structural variation of a pad retaining system in accordance with the present invention, wherein the pad retaining spring 6 is in the form of a torsion spring that is secured to the bridge 4 and will lining the brake The pad 5 is held in the raised position to form a positive locking connection with the carrier corner members 2, 3.

又亦可思及有一種構造變化例，其中該襯墊固持彈簧係呈一拉力彈簧的形式，其係支撐在一固定於該煞車鉗之彎曲的襯墊固持構件8上，如圖1所示之依據習知技術的襯墊固持系統中所示。 It is also conceivable to have a structural change in which the pad retaining spring is in the form of a tension spring supported on a curved pad retaining member 8 fixed to the brake caliper, as shown in FIG. It is shown in the pad retention system according to the prior art.
